The presence of a non-removable pickup in the design of the player.

The pickup (cartridge) is a key part for any turntable; failure of this part renders the entire device unusable. Therefore, non-removable (that is, unsuitable for replacement without disassembly in a workshop) pickups are made mainly in low-cost players, where the manufacturer tries to simplify and, accordingly, reduce the cost of construction. However, even in such models, usually, it is possible to replace the most delicate part of the pickup — the needle.

Model of the pickup (cartridge) supplied with the player. The pickup is one of the most important parts of any vinyl player, the quality of the received sound largely depends on its quality. Knowing the name of the model, you can find detailed data on it and determine how satisfied you are with this particular cartridge.

The shape of the needle in the pickup (cartridge) that the player is equipped with.

— Conical. It may also be called spherical. The simplest type of needles for vinyl players. Such needles are inexpensive, but the sound quality when using them is relatively low — due to the fact that the shape of the needle rather weakly matches the shape of the groove on the record.

— Elliptical. Elliptical needles have a narrower shape than conical (spherical) needles, which improves contact and allows, in particular, more accurate reproduction of high frequencies, and also reduces record wear. Due to the good value for money, this option is very popular.

— Linear. The most advanced variety: sharply sharpened needles of complex shape, following the contours of the grooves on the plate as accurately as possible and having the largest contact area among all types. The downside of this is the complexity in production and, accordingly, the high cost.

The signal level at the output of the pickup supplied with the player is, in fact, the power of the signal coming from the pickup to the phono stage. This parameter is necessary, first of all, in cases where the player is planned to be connected to an external phono stage: such equipment must be designed for the corresponding power of the signal coming from the pickup.

The force of pressing the needle on the plate, which the complete pickup (cartridge) is designed for.

This force depends on the rigidity (compliance) of the needle: the greater the clamping force, the harder the cartridge, respectively, the less pliable it is. It is also believed that less pressing force wears out the record less, but it cannot be said that "light" cartridges are definitely better — there are many other nuances. So in fact, information about the pressing force of a complete pickup is needed mainly in case of its replacement. Usually, the pressing force provided by the arm of the turntable is regulated within these limits, so the new cartridge must also be rated for the same values of downforce — otherwise there is a chance that the turntable will not be able to correctly align.

The weight of the pickup (cartridge) supplied with the turntable.

The weight of the cartridge determines the characteristics of balancing the tonearm to set the optimal tracking force. However, pickups in set are usually optimally compatible with the corresponding tonearms, so there are no problems with adjusting the turntable. But when buying a replacement cartridge, you should pay attention to this parameter: it is advisable that the new cartridge does not differ too much in weight from the old one, otherwise the tonearm adjustment range may not be enough for the correct balance.

Shape of the complete tonearm (viewed from on top). Modern players can have both straight and S-shaped or J-shaped tonearms. It is impossible to say unequivocally which one is better: the advantage of the first option is considered to be light weight, the second and third are long length and low resonant frequency, which reduces the likelihood of interference. Therefore, in practice, the choice depends on the specific situation and personal preferences.

The effective length of a tonearm in set is the distance from the attachment point (axis of rotation) to the stylus.

This indicator is important primarily for rotary tonearms: the longer the length, the lower the angular error, the smaller the discrepancy between the direction of movement of the track and the longitudinal axis of the pickup (for more details, see “Type”) and the lower the level of corresponding distortion. In addition, a longer length reduces the resonant frequency and reduces the likelihood of distortion. On the other hand, a longer tonearm turns out to be heavier, which requires certain technical tricks and can also negatively affect the purity of the sound. Therefore, a large length is not always a guarantee of high quality – you should also pay attention to weight (see below).

A method of transferring rotation from an electric motor to a disc player.

— Belt. Also known as "passion". In accordance with the name, such a drive uses a belt drive. Its main advantages are the uniformity of rotation combined with undemanding to the quality of electric motors, which makes it possible to achieve good sound purity even with relatively simple and inexpensive motors. It is true that passive players pick up speed more slowly and are unsuitable for special techniques like scratching; however, these moments are critical only for DJs, and in normal listening to music they do not really matter. But of the unambiguous shortcomings, one can only note the need for periodic (usually once every few years) replacement of the belt.

— Direct. In turntables with this type of drive, the disc is mounted directly on the motor shaft. This allows for very fast acceleration and deceleration, as well as the use of various special tricks, making direct drive a DJ turntable almost a must. However, such a design puts forward special requirements for the quality of electric motors, since. any irregularities and vibrations noticeably affect the sound quality. Therefore, direct drive is rarely used in "audiophile" models — in the absence of obvious advantages over belt transmission, the design turns out to be noticeably more expensive.
